I dont worry about moths. the swarms will clean any out just like they do in old bee trees. Last year I watch a new swarm moving into one of my traps. Bee were pulling on old pcs of moth silk dragging it out. it kinda looked like they were on little ropes. Lemon grass is my lure. Cheap and the bee's love the stuffhow do you keep wax moths from tearing up your drawn comb while waiting for a swarm?
